    build: Replace hard coded values for build time variables
    
    The test unit contains hard coded values for paths. However, these
    hard coded variables consider that the source code path and the
    build path are the same, something usual in autotools.
    
    These hard coded values has been replaced by build time variables
    that take the appropiate values considering different build paths.
